The momentum correction factor for the velocity distribution of laminar flow is

Solution(By Examveda Team)

In the field of fluid mechanics, the momentum correction factor (also known as the velocity correction factor) is a crucial parameter used to account for the distortion of the velocity profile near the boundary of a pipe or duct when a fluid is flowing. This factor is essential in calculations related to pressure drop and head loss in laminar flow.

For laminar flow, the correct momentum correction factor is approximately Option B: 1.66. This value reflects the influence of the parabolic velocity profile that develops in laminar flow and is commonly utilized in fluid mechanics calculations for laminar flow conditions.

Option A: 1.3 does not represent the accurate momentum correction factor for laminar flow.

Option C: 2.5 is also not the correct value for the momentum correction factor in the context of laminar flow.

Option D: None of these is not the correct answer because the correct momentum correction factor for laminar flow is indeed provided in the options, which is approximately Option B: 1.66.

It is important to note that specific conditions and sources may introduce slight variations in this value, but the value of approximately 1.66 is widely accepted and applied in practical applications involving laminar flow in fluid mechanics.
